Description

Technical Field

[0001] The invention relates to the field of automated machinery, and in particular to a combined glue filling machine and a glue filling method. Background Art

[0002] Existing glue filling machines are generally vacuum glue filling machines and normal pressure glue filling machines. When the normal pressure glue filling machine is used, glue is poured into the product under normal pressure, and then the bubbles in the glue are discharged by vacuuming and maintaining pressure, which prolongs the production cycle and reduces efficiency. When glue is poured directly by a vacuum glue filling machine, the environment needs to be vacuumed first, and then the glue is injected and the pressure is maintained. Each time the warehouse is opened, the vacuum needs to be repeated, resulting in greater energy consumption. In addition, the time consumed when pouring glue on the product is longer than the product loading time. After the product is loaded, it can only wait for the subsequent processes to be completed, and the work efficiency is also relatively low. Summary of the invention

[0003] The main purpose of the present invention is to provide a combined glue pouring machine and a glue pouring method, which realizes the adjustment of the glue pouring amount between two workstations by combining a vacuum glue pouring machine and a normal pressure glue pouring machine, thereby improving the glue pouring efficiency.

[0004] To achieve the above object, the technical solution adopted by the present invention is: A combined glue potting machine comprises a normal pressure glue potting device, a first vacuum pressure maintaining device, a second vacuum pressure maintaining device and a vacuum glue potting device. A feed port and a discharge port are respectively provided on both sides of the normal pressure glue potting device. The discharge port is communicated with the inlet of the first vacuum pressure maintaining device. A vacuum glue potting device is provided on the discharge port side of the first vacuum pressure maintaining device. A second vacuum pressure maintaining device is provided on the discharge port side of the vacuum glue potting device. Independent sealed opening and closing doors are provided between the normal pressure glue potting device, the first vacuum pressure maintaining device, the second vacuum pressure maintaining device and the vacuum glue potting device, as well as at the discharge port of the second vacuum pressure maintaining device. When the sealed opening and closing doors are closed, the internal spaces of the first vacuum pressure maintaining device, the vacuum glue potting device and the second vacuum pressure maintaining device are all in a sealed state. The first vacuum pressure maintaining device, the second vacuum pressure maintaining device and the vacuum glue potting device are independently connected to a vacuum pump.

[0005] Furthermore, the feed port of the normal pressure glue pouring device is connected to a product preheating device, and the discharge port of the second vacuum pressure maintaining device is connected to a glue curing device.

[0006] Furthermore, a first transfer device is fixedly installed in the chambers of the normal pressure glue pouring device and the vacuum glue pouring device, and a second transfer device is fixedly installed in the chambers of the first vacuum pressure maintaining device and the second vacuum pressure maintaining device.

[0007] Furthermore, the first transfer device includes a first fixed frame, a first transfer and conveying device and a positioning adjustment device. The first transfer and conveying device is fixedly installed on the upper end of the first fixed frame, and the positioning adjustment device is fixedly connected to the lower end of the first fixed frame. The positioning adjustment device is fixedly installed on a normal pressure glue pouring device or a vacuum glue pouring device. The front and rear ends of the first transfer and conveying device are also provided with a first limit assembly and a second limit assembly respectively, and the first limit assembly and the second limit assembly are fixedly installed on the first fixed frame.

[0008] Furthermore, the second transfer device includes a second fixed frame, a second transfer and conveying device, a second front end limiting device and a second rear end limiting device. The second fixed frame is fixedly mounted with the second transfer and conveying device.

The telescopic module can slide toward an adjacent workstation and extend to the discharge end or feed end of a second transfer device of the adjacent workstation.

[0010] Furthermore, a glue filling method based on a combined glue filling machine includes pre-filling of products through a normal pressure glue filling device, the pre-filling amount of glue is only a part of the glue filling required for the product, that is, incomplete glue filling is completed, and then a first vacuum pressure maintaining device between the normal pressure glue filling device and the vacuum glue filling device performs vacuuming and pressure maintaining to remove bubbles in the glue, and then secondary glue filling is performed through the vacuum glue filling device to complete the glue filling of the product. By dividing the glue filling method into two steps, the total glue filling time is shortened, and the glue filling efficiency is improved while ensuring the glue filling quality.

[0011] Furthermore, the specific steps of glue filling include: S1 preheating, loading the product onto the jig, and transferring the jig with the product to the preheating device for preheating before the product is glued, and the preheated product is connected to the jig and conveyed to the designated location through the conveyor belt; S2 is the first step of transfer, where the first transfer device in the normal pressure glue filling device is docked with the conveyor belt in the preheating device, that is, the horizontal position and the transfer position are the same, the product and the jig are taken from the jig transferred from the conveyor belt in the preheating device, and the positions of the jig and the product are adjusted by the positioning adjustment device so that the product is in the glue filling position, and the product or the jig is clamped by the clamping components on both sides of the first transfer and conveying device so that the product does not move; S3 normal pressure glue pouring, the glue pouring device installed above the normal pressure glue pouring device is inserted into the product to pour glue on the product; S4 is the second step of transfer, in which the jig and the product in the normal pressure glue potting device are transferred to the first vacuum pressure holding device through the first transfer device, and the product and the jig are transferred to the first vacuum pressure holding device. After the transfer is completed, the first transfer device of the normal pressure glue potting device is retracted, and the subsequent product is transferred from the preheating device to the normal pressure glue potting device, that is, S2 is repeated; S5: first pressure maintenance. After the first transfer device of the normal pressure glue filling device is completely out of the range of the first vacuum pressure holding device, the sealing opening and closing door fixedly installed on the first vacuum pressure holding device is started to make the internal space of the first vacuum pressure holding device form a sealed state, and vacuum is evacuated through the connected vacuum pump. At this time, the vacuum glue filling device and the second vacuum pressure holding device are evacuated at the same time; S6 is the third step of transfer, in which the product and the fixture that have completed vacuum pressure maintenance in the first vacuum pressure maintenance device are transferred by the first transfer device in the vacuum glue potting device. The transfer method is the same as that of the first transfer device in the normal pressure glue potting device. After the product is transferred, the sealed opening and closing door is closed to make the space connection between the vacuum glue potting device and the first transfer device closed. The first vacuum pressure maintenance device repeats S4 and S5; S7 vacuum glue pouring, the vacuum glue pouring device completes all the glue pouring work, opens the sealed opening and closing door between the vacuum glue pouring device and the second vacuum pressure maintaining device, connects the inner cavity of the vacuum glue pouring device and the second vacuum pressure maintaining device, and transfers the product to the second vacuum pressure maintaining device through the first transfer device inside the vacuum glue pouring device, closes the sealed opening and closing door between the vacuum glue pouring device and the second vacuum pressure maintaining device, and the second vacuum pressure maintaining device performs vacuum pressure maintaining.

[0012] Furthermore, the glue pouring time of the normal pressure glue pouring in step S3 is the pressure holding time of the first vacuum pressure holding device or the glue pouring time of the vacuum glue pouring device.

[0013] Furthermore, in step S5, the vacuuming time of the first vacuum pressure maintaining device and the time of completing the product pressure maintaining are the same as the glue injection time of the vacuum glue pouring device.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes the adjustment of glue filling amount between two workstations by combining a vacuum glue filling machine and a normal pressure glue filling machine, thereby improving the glue filling efficiency.

[0015] The glue filling amount of the vacuum glue filling device and the normal pressure glue filling device of the present invention can be adjusted according to the size of the product, so that the glue filling time is shortened to the greatest extent. BRIEF DESCRIPTION OF THE DRAWINGS
